Specification of Letters Patent.

Patented'Sept. '7, 1915.

Application filed June 11, 1915. Serial No. 33,437.

To all whom it may concern Be it known that I, MAX Sonnnsmsnn, a citizen of the United States, and a resident of New York city, in the county and State of New York, have invented certain new and useful Improvements in Looks for Trunks and Similar Articles, of which the following is a specification. I

This invention relates to a lock of novel construction, for trunks and similar articles, which is operable without the use of a key, and will effectively withstand the rough handling to which such articles are liable to be subjected.

In the accompanying drawing: Figure '1 is a front view of a lock embodying my invention; Fig. 2 a longitudinal section thereof; Fig. 3 a rear view, with the casing cut away; Fig. 1a front View of the casing with inclosed parts, and Fig. 5 a detail of one of the tumblers.

To the body of a trunk or similar article 1 is adapted to be secured, a lock plate 2 having a reinforced section 3, that is received within a mortise 4: of the trunk. Through plate 1, extends a spindle5, surrounded by a selected number of tubular spindles 6. Upon the inner ends of spindles 5, 6 are mounted, disk-shaped tumblers 7, having notches 8, while on the outer ends of the spindles are mounted dialed disks 9, 00- operating in the usual manner with a fixed index 10.

Above tumblers 7, there ismounted, on reinforced section 3 of plate 1, a sliding bar 11, passing through a guide 12, and having a lower pointed end. Springs .13 engaging bar 11, have a tendency of forcing it toward the tumblers, and into the notches 8 thereof, whenever the latter are brought into alinement with the bar. The upper end of bar 11, enters a casing 14, mounted on plate 1.

This casing contains a slide 15, movable in the same direction as bar 11 and adapted to be thrown upward by a spring 16 said slide carrying a first catch member 17. This catch member is adapted to engage a second catch member 18, mounted on a hasp 19, which is hinged to the lid or cover 20 of the trunk. Spring 16, by raising slide 15,

throws catch 17 into engagement withcatch 18, so as to lock the trunk, while upon a depression of the slide, the catches become disengaged, so that hasp 19 will be thrown Copies of this patent may he obtained for forward by its spring 21, and the lock will thus become opened.

Slide 15 is furnished with an abutment 22, which is in permanent axial alinement with bar 11, and is adapted to be engaged'thereby, when the bar is raised so as to hold the slide against movement. When however, the bar is depressed, a gap is opened up between bar and slide, which permits the free movement of the latter. In order to manually operate the slide, it is provided with a suitable button or finger piece 23.

The operation is as follows: When the lock is to be closed, tumblers 7 are so placed that their notches are disengaged by bar 11.

The latter is consequently lifted by the salient parts of the tumblers against bottom of slide 15 and prevents any movement thereof, so that in this waythe catch members 17, 18 cannot be separated. When the lock is to be opened, the tumblers are so placed that their notches become alined with bar 11. The latter will thus bedepressed by springs 13 to form a clearance below slide 15. The latter is thus free to be lowered by knob 23, so as to withdraw catch member 17 from catch member 18, against action of spring 16, and cause hasp 19 to fly open. It will be seen that when the tumblers have been set to the open position, springs 13 will automatically throw bar 11, into the notches of the tumblers, the bar thus constituting a bolt that locks the tumblers so that they cannot become accidentally disarranged.- In thisway, the'operator may now open or close the hasp by means of the finger piece 23, the same as a latch, the tumblers being entirely cutout, this being frequently desirable, especially when the trunk is not in transit.

I claim:

A look of the character described, comprising a plurality of tumblers, a slidable bar adapted to engage the same, a spring adapted to project the bar against the tumblers, a slide independent of the bar and movable in the same direction as said bar, said slide being provided with an abutment which is in permanent axial alinement with the bar, a spring adapted to retract the slide from the bar, a catch member carried by the slide, a hasp, and a coasting catch member carried by the hasp.
